US Patent 11852423 Systems and methods for tunable radiative cooling

Embodiments described herein relate to a system with an electroactive substrate, a plurality of nanoparticles, and a control unit. The plurality of nanoparticles deposited in communication with the electroactive substrate. The control unit is configured to manipulate a shape of the electroactive substrate between an unactuated mode and an actuated mode to change an absorption band or an emission band of the plurality of nanoparticles. When the electroactive substrate shape is manipulated, the absorption band or the emission band of the plurality of nanoparticles is changed to tune the system for a radiative cooling based on a current dominating wavelength.
